Good day. I ordered a 4S2P LiFePo4 battery online and it does not come with a charger. I'm wondering what specific kind of charger I need for this battery. Specs and the link of the battery are below.
Specs:
12.8V Nominal voltage 32650 LiFePo4 cell 3.2V 12000 mAh / 12Ah 4S2P Configuration 30A Common port BMS with balancing short circuit overcharge/over-discharge protection
You need a 4S LiFePO4 charger. Do not use a Lithium Ion / Lithium Polymer charger as they have completely different charge cycles and voltages.
There are many suitable chargers available, either as specialized LiFePO4 chargers, or as universal chargers with LiFePO4 settings.
The charge profile of 4S LiFePO4 batteries is very similar to that of 12V Sealed Lead Acid (car) batteries. They're often used as drop-in replacement for SLA. You can make do with a (modern) 3-stage SLA charger for charging LiFePO4's, as long as you do not exceed the maximum voltage or charging current for your 4S LiFePO4 battery and do not keep it on float/trickle charge. Using an SLA charger would be a compromise.
Ideally LiFePO4 batteries should be stored at around 50% SoC (storage charge) when they're not being used.
